A family source tells HollywoodLife.com: ‘I’m afraid for the baby’s life.’

Teen Mom 2 cast member Jenelle Evans‘ history of arrests and mischief is well known already — and it’s resulted in her mother Barbara being given temporary custody of Jenelle’s 1-year-old son, Jace. Butconversations with an Evans family source and a review of police records suggest that Barbara has had significant troubles of her own.

What’s more, her difficult relationship with her own children call into question her suitability to be Jace’s primary guardian.

“I’m afraid for the baby’s life that Barbara [has] a hold of this baby,” a family source with knowledge of the situation between Barbara, 57, and Jenelle, 19, tells HollyBaby.com exclusively. “Everybody thinks that she’s such a wonderful person because she’s trying to get the baby from Jenelle. People don’t know her. Just keep watching the show, the true Barbara will come out.”

On the MTV show, Barbara is shown constantly screaming at Jenelle and trying to gain control of situations.

Barbara and ex-husband Robert were divorced over ten years ago, and we’re told that the relationship was turbulent. Once Barbara and Robert got divorced, she took the kids far away from the family and raised them on her own. And the three Evans children have all had brushes with the law.

Both of Jenelle’s older siblings Ashleigh and Collin have had legal issues of their own — both involving their mother. Ashleigh, 22, was arrested on Sept. 26, 2006, for a Simple Physical Assault charge. “Subject was arrested after assaulting her mother,” the arrest report reads. “Ms. Evans reported that her daughter Ashleigh had assaulted her. Ms. Evans said Ashleigh has mental problems and has not been taking her medication. Ashleigh got out of control and assaulted Ms. Evans and her younger sister [Jenelle].”

Collin, 21, was picked up on Mar. 3, 2007 and faced two charges of Injury to Personal Property and Injury to Real Property. “Upon receiving a report of a domestic disturbance, I arrived to find Barbara Evans and her son Collin arguing in the front yard,” states the incident report. “Ms. Evans stated that Mr. Evans had been in an altercation with her boyfriend and punched and kicked his truck. [He also] shattered the front glass storm door.” Collin was living in a “group home” at the time of the incident, according to the report.

“It sounds like this is incredibly dysfunctional and this kid’s got like a zero percent chance of normalcy in being raised by the grandmother,” family attorney Jeff Miller tells HollyBaby.com. “The mother, who got pregnant when she was a child, still is a child and doesn’t know what she’s doing and the grandmother doesn’t seem fit.”

“But, the ultimate overriding concern is what’s in the best interest of the child,” Jeff explains. “The court would have to look at the whole big picture: the mother, who is the mother of the child, and the grandmother and look at the whole situation, household — what’s going on there. It may be that the court finds that neither of them are fit [to raise Jace].”
